In 1981 a second hand ex military vessel was purchased from the Australian Army to replace Westgate 11. This vessel was known as "SA 24" and after a lot of hard work and considerable expense the newly acquired vessel was launched at the Greenwell Point Bowling Club on the 5 September 1981. The vessel as bought was powered by twin inboard 120hp Mercruiser Sterndrive engines. SA 24 was owned by the Shoalhaven Marine Rescue Association and crewed by members of the local Royal Volunteer Coastal Patrol. In mid 1988 two Mercruiser 470 engines were installed in SA 24 at a cost of $14,500.00.

In 1991 the inboard engines were replaced by twin Evinrude Intruder 150hp engines supplied by Maurie Hartnup from Nowra Marine. Mr Hartnup was quoted as saying that there was a weight saving of around 1,400 pounds, and the top speed of the vessel increased from 32 knots to just over 40 knots. The Shoalhaven Marine Rescue Association adopted a policy of regularly replacing the outboards, usually at twelve month intervals although this time frame increased as the vessel aged and the cost of replacement engines increased. The engines used later in its life were generally Mariner of Mercury outboards.

SA 24 remained in service with Shoalhaven Marine Rescue Association until December 2002 when it was retired and sold, having been replaced by TSRV Crookhaven which was delivered in March 2003.

The pictures below were taken in March 2002, shortly before SA 24 was retired and show her in her final livery.
